Cognitive testing

HeeSun Choi, Jonathan Kasko, Jing Feng
Background and Objectives : Mobility is a critical factor that influences older adults' independence and well-being. Older drivers may experience increased crash risks due to age-related cognitive declines. Ensuring safe driving practices among older drivers is important to maintain their mobility without sacrificing safety. Investigations for an effective assessment technology that can inform older drivers' risks associated with cognitive declines are warranted. This study aims to identify attentional deteriorations that may underlie crashes in various situations...

In the general population aortic stiffening, assessed by carotid femoral pulse wave velocity (cf-PWV), is associated with cognitive dysfunction (CO/DY). Data in chronic kidney disease (CKD) are limited. This study tests the hypothesis that large artery stiffness and microvascular damage in CKD patients are related to the damage of brain microcirculation reflected by impaired cognitive function. A cross-sectional study enrolled 151 patients (mean age 58.4 years; 64.5% males; 44 patients with CKD stage 1; 47 with stage 2; 25 with stage 3; and 35 with stage 4)...

Recognising an object involves rapid visual processing and activation of semantic knowledge about the object, but how visual processing activates and interacts with semantic representations remains unclear. Cognitive neuroscience research has shown that while visual processing involves posterior regions along the ventral stream, object meaning involves more anterior regions, especially perirhinal cortex. Here we investigate visuo-semantic processing by combining a deep neural network model of vision with an attractor network model of semantics, such that visual information maps onto object meanings represented as activation patterns across features...

BACKGROUND AND AIMS: Arterial remodelling aims at normalising circumferential wall stress (CWS). Greater CWS in the carotid artery has previously been associated with the prevalence and severity of cerebral small vessel disease, a major cause of ageing-related cognitive decline. Here we test the hypothesis that greater carotid CWS is associated with poorer cognitive performance. METHODS: We studied 722 individuals (60 ± 8 years, 55% men, 42.5% highly educated, blood pressure 137 ± 19/77 ± 11 mmHg, n = 197 with type 2 diabetes) who completed a neuropsychological assessment and underwent vascular ultrasound to measure the intima-media thickness (IMT) and interadventitial diameter (IAD) of the left common carotid artery at a plaque-free site...

Propofol is the most widely accepted intravenous anesthetic available for clinical use. However, neurotoxicity of propofol in the developing brain has been reported. This study investigated the effects of propofol on cognitive function in normal healthy adult mice. Thirty-three GFP-LC3 adult mice were included. Propofol was injected for anesthesia (n= 22). The sham control (n= 11) received intralipid injections. The mice completed a Y-maze test on 3 and 7 days after being anesthetized. Western blotting, immunofluorescence staining, and transmission electron microscopic (TEM) analyses were performed with their hippocampi...

BACKGROUND: Older adults with cognitive impairment are at higher risk for various health problems. Although previous studies have suggested going outdoors more frequently might be effective to promote health, no longitudinal studies have examined objectively measured outdoor time in this population. This study examined the relationships between changes in objectively measured outdoor time and physical, psychological, and cognitive functions among older adults with cognitive impairments...

Motivation improves performance, pushing us beyond our normal limits. One general explanation for this is that the effects of neural noise can be reduced, at a cost. If this were possible, reward would promote investment in resisting noise. But how could the effects of noise be attenuated, and why should this be costly? Negative feedback may be employed to compensate for disturbances in a neural representation. Such feedback would increase the robustness of neural representations to internal signal fluctuations, producing a stable attractor...

OBJECTIVES: To generate a scoring algorithm weighted on the preferences of consumers for assessing the quality of care in nursing homes (i.e., aged care homes or institutions) in six key domains. METHODS: A discrete choice experiment was undertaken with residents of nursing homes (n = 126) or family member proxies (n = 416) in cases where severe cognitive impairment precluded resident participation. Analysis was undertaken using conditional and mixed logit regression models to determine preferences for potential attributes...

Alzheimer's disease (AD) is a devastating neurodegenerative disease characterized by protein aggregates of amyloid β (Aβ) and tau. These proteins have normal physiological functions, but in AD they undergo a conformational change and aggregate as toxic oligomeric and fibrillar species with a high β-sheet content. Areas covered: Active and passive immunotherapeutic approaches are among the most attractive methods for targeting misfolded Aβ and tau. Promising preclinical testing of various immunotherapeutic approaches have yet to translate to cognitive benefits in human clinical trials...

BACKGROUND: Using more than one psychotropic substance is accompanied by increased risks for psychiatric and physical disorders. Accordingly, deficits in basal cognitive functions have been consistently associated with polysubstance use (PSU), whereas little is known about potential impairments in more complex socio-cognitive skills, which are relevant for daily-life functioning. Therefore, we investigated the effects of toxicological validated stimulant PSU on social cognition under consideration of potential cumulative effects...

Cerebral microbleeds (CMBs) have been identified as an important manifestation and diagnostic marker of cerebrovascular disease, but there are also some controversies about the impact of CMBs on cognition. The current cross-sectional study aimed to clarify the relationship between CMBs and cognitive impairment in patients with ischemic cerebrovascular disease. One hundred and fifty patients with lacunar infarction or transient ischemic attack were screened, and all of them were scanned by brain MRI. In the end, 125 patients who were divided into a CMBs group and a non-CMBs group were selected and completed the cognitive tests...

BACKGROUND: In adults, xenon has only minimal hemodynamic side effects when compared with other anesthetics. Moreover, in preclinical experiments, xenon has been demonstrated to possess cardio- and neuroprotective properties. Altogether, the favorable hemodynamic profile combined with its potential for organ-protection could render xenon an attractive option for anesthesia in children with cardiovascular compromise. AIMS: The aim of this study was to explore safety and feasibility of sevoflurane-augmented xenon anesthesia in school-aged children and to assess early postoperative neurocognitive effects of xenon-sevoflurane and sevoflurane anesthesia when compared to a control group that did not have anesthesia...

Older adults frequently report pain; cross-sectional studies have shown that pain is associated with worse cognitive function. However, longitudinal studies are lacking. We prospectively studied 441 participants without dementia, including 285 with pain, aged 65 years and older, enrolled in the Central Control of Mobility in Aging Study, a prospective cohort study. We analyzed the longitudinal association between pain (Medical Outcomes Study pain severity scale) and major cognitive impairment (Repeatable Battery for the Assessment of Neuropsychological Status and the Trail Making Test Delta) using Cox regression analysis adjusted for age, gender, ethnicity and education...

The abuse of amphetamine-type stimulants (ATS) has become a global public health issue in recent years, these new-type drugs can cause addiction and serious cognitive impairment. However, there are no effective methods for the prevention and treatment of ATS addiction at present. Repetitive transcranial magnetic stimulation (rTMS) is a painless and non-invasive new therapeutic approach that has been used for the treatment of depression and other neuropsychiatric disorders, but whether it can be used to treat drug addiction is unclear...

The apolipoprotein E (APOE) epsilon 4 isoform has been associated with a significantly greater risk of developing late onset Alzheimer's disease (AD). However, the negative effects of APOE-ε4 allele on cognitive function vary across the lifespan: reduced memory and executive function have been found in older individuals but, paradoxically, young APOE-ε4 carriers perform better on cognitive tests and show higher neural efficiency. This study aimed to assess the association between APOE genotype and saccade latency using a prosaccade and antisaccade task in young individuals (N = 97, age: 17-35 years)...

Being sexually aroused may be an important risk factor contributing to sexual decision making. Dual-process cognitive models, such as the reflective-impulsive model of Strack and Deutsch (2004), could be used to explain the effect of sexual arousal on intentions to use a condom. In this study, we investigated whether explicit and implicit attitudes toward condom use can predict intentions to use a condom when participants are sexually aroused and not aroused. In a within-subjects experimental design, male participants (N = 27) watched both a neutral and an erotic movie clip in counterbalanced order...
